Description
Technical field
This utility model relates to medical operating articles for use technical field, belongs to one 3D printing and exempts to sew up biliary duct jejunum anastomotic scaffold.
Background technology
It is complicated that tradition opens the operation of abdomen pancreaticoduodenectomy, operation wound is large, and biliary enteric anastomosis, Pancreaticoenterostomy are the committed steps of pancreaticoduodenectomy, because Cholangio-jejunostomy mouth or (with pancreas intestinal anastomotic stoma) Cholangio-jejunostomy mouth fistula, the Pancreaticojejunostomy entirely do not caused that heal is postoperative common severe complication, general incidence rate is 5 ~ 20%, Pancreaticojejunostomy mortality rate can reach 20 ~ 40%, and medical expense is expensive.
In recent years, domestic and international minority comprehensive large hospital peritoneoscope or the large case report of Leonardo da Vinci's robotic surgical device (Wicresoft) pancreaticoduodenectomy show, Wicresoft's pancreaticoduodenectomy opens abdomen pancreaticoduodenectomy than tradition, not only post-operative recovery is significantly accelerated, and postoperative short-term, long term survival rate are even better.But Wicresoft's advantage of peritoneoscope and Leonardo da Vinci robot pancreaticoduodenectomy, do not accepted extensively by outer scientific cirle, its main cause is peritoneoscope pancreaticoduodenectomy Cholangio-jejunostomy, the complexity of pancreas Surgical healing and technical difficulty, makes operating time significant prolongation; Our experience shows: especially as ductus pancreaticus diameter <3mm or marginality ductus pancreaticus, ductus pancreaticus is implemented very difficult to mucosa anastomosis under peritoneoscope, the probability of postoperative generation pancreas fistula significantly rises, pancreas Digestive system contact methods of anastomosis have to be selected (as binding pancreas intestinal/pancreas stomach, pancreas intestinal side or end end, pancreas stomach embedding inosculating,), thus increase the complication such as postoperative digestive tract hemorrhage; The technical bottleneck be difficult under although Leonardo da Vinci robot amplifies 10 times of surgical field of view by its three-dimensional and interior wrist breaches peritoneoscope flexibly, shorten the identical time, but, domestic only have 26 machines, and judgement that whether suture is definitely strained becomes very difficult during the disappearance of tactile feedback makes to coincide, tension can be broken suture or cut and organize, and crossing pine can cause fistula of operative incision, and reported literature also confirms peritoneoscope and robot postoperative pancreatic fistula, the incidence rate of leak does not significantly reduce.Therefore not only traditional pancreaticoduodenectomy biliary enteric anastomosis, Pancreaticoenterostomy remain a Research Challenges and focus, and in current Wicresoft, precisely, epoch of effective liver and gall pancreas surgery development, peritoneoscope and Leonardo da Vinci robot biliary enteric anastomosis, Pancreaticoenterostomy research and innovation are significantly more urgent.
The biliary enteric anastomosis of current clinical practice, Pancreaticoenterostomy be all set up with sew up, on the basis of tie a knot, the mode of optimal reconstruction of digestive tract has a kind of methods of anastomosis, can exempt the operation that these are relevant with stitching.Sew up nature and have pinprick, the elasticity of knotting, the tearing of organizational structure, the defects such as the prolongation of operating time.Utilize a kind of support, rear connection is inserted at the two ends of intending coincideing separately and can fixes, two broken ends of fractured bone self-growths connect, so both stitching can be exempted, avoid that the technical bottleneck being difficult to overcome all is existed to peritoneoscope or Leonardo da Vinci, ensure that the unobstructed of anastomotic stoma by support again, avoid the complication that may cause because of anastomotic stoma edema or identical defect.Research in the past have also been made a lot of trial in this respect, but what also do not have molding so far can the product of clinical practice, reason is that Cholangio-jejunostomy, pancreas Surgical healing are unlike gastrointestinal anastomosis, gastrointestinal anastomosis is because tissue plasticity is strong, anastomotic stoma size is relatively fixing, anastomotic stoma large, therefore clinically generally applies anastomat; And the shape and size of biliary tract, ductus pancreaticus and bore, because disease character, stadium difference are widely different, and ductus pancreaticus, bile duct poor plasticity, caliber is little, therefore, the anastomosis ring that the bore having fixed mould to produce as gastrointestinal anastomosis device is consistent or anastomat, and be not suitable for clinical.Cross and slightly easily make it strut excessively and affect Tissue Blood confession, mistake detailed rules and regulations can cause fixes loosely.
Utility model content
The purpose of this utility model is to provide one 3D printing and exempts to sew up biliary duct jejunum anastomotic scaffold, its structure is simple, easy to use, Be very effective, it is according to the reconstruction of preoperative image data data, can print with individual patients bile duct size to the biliary duct jejunum anastomotic scaffold mated with 3D printing technique, by these two ends with plush copper and the pipe outer wall support tube with projection, can realize exempting from sutured anastomosis, thus decrease Lou and narrow risk, greatly reduce operation easier and risk simultaneously.
For achieving the above object, this utility model takes following technical scheme:
One 3D prints and exempts to sew up biliary duct jejunum anastomotic scaffold, it is characterized in that: the projection that this biliary duct jejunum anastomotic scaffold comprises support tube and protrudes at support tube outer wall, plush copper is connected with at the two ends of this support tube, be connected with drainage tube in the outer end of this plush copper, this biliary duct jejunum anastomotic scaffold makes with degradable biomaterial 3D printing technique.
Wherein, described plush copper, spherical in semicircle, arc surface is outside two ends.
Wherein, upper and lower projection is respectively equipped with at support tube outer wall near plush copper place, two ends.
Wherein, described degradation material comprises: biocompatible materials or degradable biomaterial, and wherein biocompatible materials is silica gel.
The biliary duct jejunum anastomotic scaffold of individuation degradation material is manufactured with 3D printing technique, when carrying out robot and peritoneoscope Cholangio-jejunostomy, release is sewed up, make to coincide simply, anastomotic stoma need not be sewed up, greatly save the time, biliary duct jejunum anastomotic scaffold effectively prevent the direct effect of Digestive system to anastomotic stoma simultaneously, exempt from suturing skill and also ensure that anastomotic stoma has sufficient blood to supply, also be suitable for bile duct or the ductus pancreaticus broken ends of fractured bone to dissociate the hilar bile duct of difficulty, stones in intrahepatic bile duct and the heavier case of pancreas inflammatory, biliary duct jejunum anastomotic scaffold can also ensure the unobstructed of anastomotic stoma, avoid anastomotic stoma because of scar hyperplasia, the anastomotic stricture that cicatricial contracture causes, improve the late result of Cholangio-jejunostomy.Thus be expected to solve peritoneoscope and the key difficulties problem of Leonardo da Vinci robot in Cholangio-jejunostomy, make that operation is safer simple and conveniently to be carried out, improve the therapeutic effect relating to the complicated liver and gall pancreas Minimally Invasive Surgery of above-mentioned surgery reconstruction of digestive tract.
The beneficial effects of the utility model are: its structure is simple, easy to use, Be very effective, it is according to the reconstruction of preoperative image data data, can print with individual patients bile duct size to the biliary duct jejunum anastomotic scaffold pipe mated with 3D printing technique, by these support tubes with projection and plush copper, can realize exempting from sutured anastomosis, thus decrease Lou and narrow risk, greatly reduce operation easier and risk simultaneously.
